Question about 2003 Ford Expedition
The front blower in my 2004 Ford Expedition makes a rattling/knocking sound when set to 2, 3 or 4. You can't hear it when its on 1 but it gets louder and much more aggravating when the fan speed is increased. Can someone tell me what this probably is and where the front blower assembly is located?
The squirrel cage is probably loose on the blower motor shaft.
here's 2003, don't have 04.

Either the motor is defective or its rubbing against a loose motor panel or there may be somthing stuck in it. Regardless have it checked out.

if the noise is coming from the bottom end of the motor then you have either bad connecting rod bearings or bad crank bearings.if when you snap the throttle you hear a double knock then its connecting rod bearing if not then its crank bearing.a collapsed piston can sound low in the engine and its usually a dull knock noise.if you have the engine running and the noise is there and you pull off one plug wire at a time(and reconnect it after checking) and the noise goes away or mostly goes away with the wire unhooked then the cylinder that the noise changed is the cylinder that has a bad piston.

depends on what exactly it sounds like if its loud and a hard soundin knock you may have a rod knockin if its light soundin it could be a noisy lifter overheating or too low of octane in uur gas

That doesnt sound good. Check the engine oil level and top up as necessary. If the noise is still there, then you should take it to a mechanic to check. It could mean that you need to either replace the engine or overhaul it. Hope that helps

the blower motor is like round cage and the only way to get to it is to take appart the dash. not the insterment cluster but the top and through the glove box is probably the only access. i doubt you will find a schematic just take lots of pictures while taking appart of what each screw looks like as it comes out. most the heater vents are in your way taking them out is not only screws but plastic barbs. just take every thing appart that is plastic and keep track of where it goes the cage you want is dead center of the dash. you dont need to take it out just get access to it. also what ever got there probably fell from one of the vents that blows onto the windshield so the top of dash removal may be easier if all you need is access to pull out some trash.
